00:01:40 Two-way radio ¿Do you read me there?¿ Cuts off¿

Cuts in for a half second, cuts out¿ a few times

00:03:54 Testing mic. Test one two¿ Back and forth over two-way. Loud and clear then cuts out. This process is repeated until between long periods of silence until

00:16:24 Will you please blown your soft and come to the surface

00:16:30 Blow the soft balance? (yes ,please and then shut her off.)

Ok the diver is going to release you so I just want to make sure the screen is off and thrusters disabled. (The screen is not on) Roger that.

Asides about vhfs

00:17:43 Ok, Scott you¿re cut loose. If you want to enable your thrusters and motor towards the sun, towards that end of the pier¿ rotate to your port, your left and please stay clear of the pier.

Radio voice guiding Scott around pier.

Scott gives readings. Altimeter etc¿

Going back and forth as Scott submerges.

00:20:34 Directing Scott closer to rocks
00:21:00 Directing Scott toward photo-ops

Lots of back and forths as Scott submerges ¿Can I use the lights?¿ etc¿

Long periods of blank tape until

00:51:40 On hardwire headset. Directing Scott to end of dock to Geographic photographer¿. More blank tape¿

00:52: 50
Hello John? (Yes) This is Alex Chadwick from Radio Expeditions tell me what it¿s like down there.

00:52:56 (faint)
It¿s uh, wonderful. It¿s interesting at this point because the rocks at the surface look a little bit farther away at this point than they do when you¿re looking under the water surface. It¿s real exciting and I just can¿t wait to get down. Every once in a while an animal, a seal lion will jump in and whiz by. It¿s just a very peaceful, very good feeling.

00:53:29 Radio voice-You¿re about to dive I think¿.
Scott- Gives life support readings

00:54:28 John? Sylvia here. ( Sylvia, how are you) I¿m just fine we have Chip.. here the geographic photographer par excellance. I¿m going to get him to say hello.

Chip and John talking.. Sylvia and John talk about the photos and sea lions. John can¿t hear the sea lions except underwater. Rotates around to take pictures. Trying to a get a feel for the foot pedals.

Long period of silence until John takes off at 01:06:46
Begins dive after giving 18% O2 and gives bellows a turn.

More silence¿..

01:17:08 I mean the fact that you can stay in here at any depth as long as you like essentially during the day makes it a different feeling. And I was worried that being in the deep worker wouldn¿t give you the sort of flexibility that you have as a swimmer scuba diving but you clearly can move around very easily and this dome gives you sort of a wonderful almost 360 view. It¿s very relaxing very comfortable. Not to stay scuba diving isn¿t but this is very comfortable. (I guess you¿re staying a lot warmer too?) You stay warm , in this kind of water you definitely do.

01:18:05 Wow it¿s just great, I¿m coming up on some rocks and it¿s just, whoa. All of a sudden you get pretty close or it feels as if you¿re pretty close. (Have you hit the bottom yet?) Well, a couple times I¿ve gone down and hit bottom. It¿s just rock at least where we are.

Going out a little further, joking back and forth on radio
00:19:22 Wow, it¿s just wonderful when these sea lions kind of bust out from nowhere.

Heading back 01:20:19


01:22:56 You know it¿s very disorienting when you get down here real deep and you can¿t see the sun anymore.

01:25:54 Talking about the sea lions barking and how John can¿t hear them barking. SE suggests a hydrophone on the outside of the submarine. She asks if he sees any fish. No, they decide it¿s probably because of the sea lions.

Very end of tape around 01:47:00 is faint voices- inaudible
